Specification forming partof Letters Patent No. 36,390, dated September 9, 1862.:

To all whom, it may concern.-

Be it known. thatI, U L-m BILLINGS, a citizen of the United States of America, and a resident of New Bedl'ord, in the county of Bristol and State of Massachusetts, have invented a new and-useful or I'mproved Machine for Swaging or Forming Blanks for Horseshoes; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is atop view, Fig. 2 a front elevation, and Fig. 3 a side elevation, of it. Fig. 4 is a vertical section taken through the up: right reducing and curving rollers. Fig. 5 is a vertical longitudinal and central section of the machine. Fig. dis a top view,' and Fig. 7 a rear view, of the movable buttress to be hereinafter described, the cam and spring for operating the buttress being shown in Fig. 6; Fig. 8, a horizontal section of the central or lateral reducing CillllOl roll.

The nature of my invention consists in an improved horseshoe-blank former or combination of adjustable swaging and creasing rol ls, and a movable buttress arranged together, and with mechanism for operating them, sub-- stantially as hereinafter described.

In the drawings. A exhibits the frame of the machine. \Vithin this frame are placed two shafts, B 0, arranged with their axes parallel and perpendicular to a third shaft, D, which is also placed within the frame and has its journals a a supported in boxes b I), provided with adjusting-screws .c c, and soapplied to the frame A as to be capable of being moved in a direction toward the two shafts B C. The boxes at d of the upper shaft, B, are also provided with adjustable or stop screws e c, and are so applied to the frame A as to be capable of being elevated within the same as circumstances may require, thesaid two shafts l3 and 0 being geared together by two spurgears, E F. Furthermore, there is a beveled pinion, G, fixed to one end of the shaft 0 and made to engage with a beveled gear, H, applied on the vertical shaft D, the whole being arranged as shown in the drawings.

Two swaging-rolls, I K, are carried respectively by the shafts B and G, these rollers being so formed as not only to impart to-abar of iron,whilc they may be in operation thereon, the proper variable thickness of a shoe- 2' blank, but in the meantime to suitably crease or groove it, the parts for creasing it being shown at f f as extended from the periphery of the upper roll. The creases that are formed are those which, upon the shoe being attached to a horse.s foot by nails, receive the heads thereof. The lowermost of the rolls is made with a flange, 9, extending from one side of it and lapping over the upper roll. The lateral or central roll, L, carried by the shaft D, acts in conjunction withthe said flange in determiningthe variable width of the shoe-blank while the'bar from which such blank is to be formed may bepassing between them and the vertical rolls.

In rear of the bite of the rolls'there is an.

adjustable stop, M, against which the end of the metallic bar is forced preparatory toits reduction by the rolls. Furthermore, the' movable. buttress N is placed between the stop hi and the rolls, and is constructed with a,

riglit=angular notch, k, to receive the blank,

bar and bear against one edge, as well as the upper side of it. This buttress is carried by a lever, O, to whichit is fastened by a clampscrew, Z. The said lever has its fulcrum m at one end, and in an arm, a, projected from the frame of the machine. A springgo, serves t-o'press the lever toward and against a cam,

p, which is fixed on the shaft D. The object of the buttress N is to prevent the shoe-blank from curling or heading laterally while being formed.

The rolls are so made that while they may be revolving they will allow the shoe-blank rod preparatory to its reduction to be passed between and against the stop Soon afterward the rolls seize it, retractit, and compress it into the required formfthe blank so made being subsequentlyseparated from therod. I"

would remark that. during this action of the rollers the metallic rod is supposed to be at a red heat. While the rolls may be moving into positions to allow of the introduction of per surface of the rod, and while in such position it will effectually prevent the blank from (ranting or bending under the action of the rollers.

I am a-ware that rolls have been used for swaging metal into various shapes, both in its width and thickness, therefore I do notclaim such as my invention; but

' I claim--- 7 My improved horseshoe-blank former, or

combination of the adjustable swaging and creasing rolls I K L, and a movable buttress,

N, constructed, applied, and arrmigedtogether kind with mechanism for operating them, subs'tuntiall y as hereinbefore described. URTAH ILLiNes.
